With the new sensor system Heimatec.Cybercon 4, different tool parameters can be measured and forwarded to a monitoring station. The collected data can be used for maintenance purposes and to prevent machine failures.
Digital tool management becomes a reality with Heimatec.Cybercon 4.
The sensor system, which has been integrated into the driven Heimatec tool, can be used to measure various tool parameters such as operating time, rpm, temperature or humidity. As the company explains, the collected data are transmitted wirelessly to the monitoring station after a defined time cycle via Bluetooth Low Energy technology and can then be used for evaluation and maintenance activities.
In addition, by means of a moisture sensor (“Tsunami alarm”), the entry of liquids such as cooling lubricants into the tool or the machine is immediately reported to the control center so that major damage or machine failures (idle time) can be prevented. By using the monitoring software, tools equipped with the solution can be supervised to help manage maintenance cycles. For example, checks can be made as part of an intelligent tool management as to when the next service application is required and what measures need to be taken.
Zykloidgetriebe von Nabtesco leisten nicht nur in Robotern hervorragende Arbeit, sie ermöglichen auch die exakte Positionierung von Rohlingen und Werkzeugmagazinen in Werkzeugmaschinen.
Die Zykloidgetriebe zeichnen sich durch eine sehr hohe Positioniergenauigkeit und Steifigkeit sowie eine besonders kompakte Bauform aus. Nabtesco bietet nicht nur diverse, in den Baugrößen abgestimmte Einbausätze mit und ohne Schrägkugellager an. Für Anwendungen mit geringem Bauraum finden Anwender außerdem zahlreiche Exzentergetriebe mit Hohlwelle im Produktprogramm: Hier lassen sich Datenkabel, Versorgungsleitungen oder Antriebswellen einfach und platzsparend durch die Mitte des Getriebes führen.
Dank der hohen Drehmomentleistungen, dem minimalen Spiel von weniger als einer Winkelminute und sehr hoher Steifigkeit sind die Zykloidgetriebe in der Lage, selbst hohe Traglasten ohne Nachschwingen schnell und präzise zu positionieren. Diese besonderen Eigenschaften verdanken die Getriebe ihrem Funktionsprinzip mit zweistufiger Untersetzung: Die doppelten Kurvenscheiben reduzieren die Drehzahl, so dass kaum Vibrationen entstehen. Da die Kraft sich durch die Rollen-Exzenter-Konstruktion zudem gleichmäßig verteilt, überstehen die Getriebe sogar eine Schockbelastung vom Fünffachen des Nenndrehmoments.
Getriebeserien für unterschiedliche Anwendungen erhältlich
Nabtesco fertigt verschiedene Baureihen seiner Zykloidgetriebe, die unterschiedliche Besonderheiten aufweisen. Die neuen RF-P-Einbausätze eignen sich z. B. ideal für den Einsatz in automatischen Werkzeugwechslern (ATC), da sie für Hochgeschwindigkeitsanwendungen auf engstem Bauraum konzipiert wurden. Speziell auf die exakte Positionierung von Magazinen in Werkzeugmaschinen sind dagegen die Getriebe der RA-EA/EC-Serie ausgelegt. Diese Ausführung hat eine sehr hohe Überlastfähigkeit, hohe Untersetzungen und eine angepasste Gehäuseform, die eine schnelle Integration in Scheiben- oder Kettenmagazine ermöglicht. Die ganzzahlige Untersetzung sorgt für eine punktgenaue Positionierung des Werkzeugwechslers.
Die RS-Serie findet häufig im Antrieb horizontaler Drehtische Verwendung. Diese hochpräzisen Hohlwellengetriebe mit integriertem Winkelgetriebe sorgen für die exakte Aufbringung von Schweißpunkten im Zehntelmillimeter-Bereich. Das RS-Getriebe ist für sehr schwere Lasten ausgelegt und kann dank seiner gusseisernen Basis einfach auf dem Boden montiert werden, so dass ein stabiler Stand gegeben ist. Die RS-Serie unterstützt Nenndrehmomente zwischen 2.548 und 8.820 Nm sowie Beschleunigungs- bzw. Bremsmomente bis zu 17.640 Nm. Das integrierte Hauptlager erlaubt den Einsatz in Anwendungen mit Axiallasten von bis zu 9 t.
Die RH-N-Baureihe ist aufgrund ihrer hohen Leistungsdichte besonders für hohe Traglasten geeignet. Das Getriebe lässt sich flexibel an alle marktführenden Servoantriebe anpassen und ist wegen seines innovativen Tribologiekonzepts extrem wartungsarm. Da Antriebsritzel und ein Motorflansch für die gängigsten Motortypen in den Getriebekopf integriert sind, kann der Konstrukteur das Getriebe einfach per Plug-and-Play in die Anwendung einsetzen.

Spray like the big boys: Take compact, refillable Mini Sprays with you and use them anywhere – The perfect addition to the Motorex spray range.
Motorex developed its versatile Hi-Tech sprays for daily professional use. If you just need a little, but it has to be handy at all times, the new Mini Sprays are just the thing.
Motorex refill system
The idea for Mini Sprays, which can be refilled as often as users want, stems from the fact that large (500 ml) spray cans are not always convenient to use. Each Mini Spray kit consists of three empty 50-ml spray cans. Each can has a base label, and the package contains a sheet of self-adhesive labels for the most commonly used sprays from the Hi-Tech range.
Now any user can put together a personalized set of the sprays they use most often. Just choose the right label from the sheet and apply it to the space intended for it on the Mini Spray. The refillable MINIS are filled straight from the large standard spray can, which functions as a dispenser. Just place the empty Mini Spray on a firm, level surface, remove the spray nozzles from both cans, shake the dispenser and fill the small spray.
Always at hand
Many users told Motorex how inconvenient it can be to carry a large spray can while assembling equipment or working in cramped spaces. The company responded by introducing a REFILL SYSTEM for its nine most popular Hi-Tech sprays.
100 % Swiss made by Motorex
All Motorex sprays are developed in Langenthal, tested in professional real-world practice and then produced at our own production facilities. This approach enables Motorex to offer the right spray for every application.

Delcam has partnered with Cranfield University, Airbus Group and the University of Bath in a major project looking at the use of Additive Layer Manufacturing (ALM, more commonly known as 3-D printing) to revolutionise the production of titanium alloy aircraft components.
The £995,000 project, which began at the Cranfield University Welding Engineering and Laser Processing Centre in January 2014, is looking at the industrial potential of RAWFEED, Rolling Assisted Wire Feed Direct Deposition for Production of High Value Aerospace Components. The ALM process would reduce waste in the manufacture of titanium components from the current 80-90% to 30-35%, and increase production speed 50-fold compared to components manufactured using conventional methods.
Step by step
The RAWFEED process uses a welding torch to deposit a continuous bead of material on a titanium baseplate, creating the first layer of the component. The layer is allowed to cool and is then rolled to enhance the material’s properties. This process is repeated until the required 3D shape is completed. Managed by Airbus and supported by £630,000 support from the UK Technology Strategy Board, the research is looking to validate a cost model and define the machine architecture and specification to exploit the industrial potential of this emerging technology.
Delcam is providing the high quality control software for the project over a wide range of machine tool and robotic platforms. The University of Bath’s Laboratory for Integrated Metrology Applications (LIMA) will develop a measuring system that will help control and quality assure the process. Curtis Carson, Head of Systems Integration – Manufacturing Engineering at Airbus Group commented: “Airbus currently procures £250m of these components every year, so the savings in terms of waste and production efficiency are enormous. We are proud to be associated with this cutting edge technology project, which is a continuation of the work to date on additive layer manufacturing, and confirms its potential for industrial scale application. RAWFEED could dramatically transform the way high-value aerospace components are manufactured, as part of lean and efficient UK industry of the future. We, and our partners, are very grateful for the support of the Technology Strategy Board, which is continuing to join us in investing in innovation in the UK aerospace industry.”

Micron-scale resolution – with today’s laser technology, resists for microcomponents can be produced cheaply and quickly. With a new compact laser system, individual trays are exposed directly.
LPKF, in cooperation with the Slovenian company Aresis and the University of Ljubljana, is developing new low-cost, fast processes for structuring of microcomponents. Maskless UV laser direct imaging (LDI) of photosensitive polymers (photoresists) offers numerous advantages over classic mask projection techniques.
Research and development in the field of microfluidic devices and micromechanical systems benefit from fast prototyping processes such as LPKF-LDI. Lab-on-a-chip devices help miniaturize processes and reduce liquid sample sizes as well as waste. This opens up tremendous possibilities for the LDI process in medicine, biology, chemistry, and physics. The applications are diverse – blood and cell analysis, medical diagnosis and screening, sensors (chemical, biological, environmental, and weapons technology; automotive engineering), synthesis of chemicals, and physical experiments.
Manufacturing microfluidic components
Three processes are mainly used to manufacture microfluidic devices on the scale of tens of nanometers to more than a hundred micrometers. The currently prevailing method of photolithography is primarily recommended for large-scale production. For frequent layout changes or low production quantities, though, the process is much too elaborate. In the electron beam method, the structures are written directly onto a resist. The electron beam has resolutions of between 20 and 50 nm. However, special resists, conductive substrates, a high vacuum, and an extraordinarily large amount of time are required for this process. With Laser Direct Imaging (LDI), a scanner-guided laser beam writes structures directly, rapidly, and precisely onto the photoresist without using a mask. This results in extremely smooth side wall edges.
LDI: fast, flexible, and precise
The LPKF ProtoLaser LDI can be used for production of microfluidic devices as well as MEMS, BioMEMS, integrated optics, and photonic experiments with microscale structures. In terms of precision, LDI surpasses all comparable systems for mask projection. Investment costs are considerably lower than for electron beam lithography and for numerous mask alignment systems. LDI even enables structuring of elements with web widths of less than a micron.
However, there are many more features: substrate exposure with a focused 375-nm TEM00 UV laser beam, which can also be used for standard UV resists; software-controllable laser focus (1 – 3 µm) for changing precision requirements; and an integrated camera for fine positioning of substrate and automated self-calibration as well as stitching mechanisms for real-time manufacturing of large samples.
The launch of the ProtoLaser LDI product will coincide with the presentation at MicroTAS in San Antonio, USA, from October 26 to October 30.

At the base of the specifications of the new s100 product line just unveiled by Bumotec, a simple idea: to create a product with maximum productivity in a minimal floor space. This while ensuring both quality of work and accuracy superior to the constraints of the watchmaking world. After 4 years of development, the s100mono and s100multi machines are being marketed and results exceed expectations. Meeting with Charles Dénervaud, responsible for marketing of the near-Fribourg based company.
Bumotec has developed a new concept of work with two spindles that is applied to several machines. The s100mono is a 3-linear-axis machining centre equipped with two working spindles. The s100multi machine has 4 workstations each with two spindles. In this case, the pallet holding the part moves from one position to another. The logic is the same as for a transfer machine. It is equipped with 144 tools, enabling significant gains on set-up times and unbeatable productivity. In this post, we will mainly talk about the s100mono version.
Lightning accelerations and maximised productivity
The machine is able to offer accelerations of more than 3 G (tested up to 5G). Our interlocutor says: “All the elements of the machine are known and proven. It offers a lot of possibilities and we discover new applications or methods enabling significant productivity gains every day”. And if nowadays the tools are not designed to work under those extreme conditions, it is evident that trends moves toward that direction and Bumotec is already prepared. To be able to control such a reactive machine, the company chose the Bosch Rexroth MTX Performance NC.
To benefit of hidden time to the maximum
In comparison with a classical single spindle machine, tests show very important cycle times improvements. When one requires 13 minutes with this technology, the s100 mono machine needs less than 8 minutes and an s100 multi only needs 2 minutes.
Next opportunity to meet the specialists of Bumotec and to discover this new solution are Prodex (halle 1.0, stand B19) and Baselworld in early 2015 (Halle 4U, Stand E11).
